Noisy ipmi0 after bootup?

Hi,
I notice that when I boot NetBSD install media on recent hardware
where it can find e.g. an ipmi0 device, it's spews console
messages a short while after boot-up, apparently only to tell the
user that everything is normal, e.g.
ipmi0: normal state on 'Temp 9'
ipmi0: normal state on 'Temp 2'
ipmi0: normal state on 'Temp 1'
etc. Since this is on the console, these get duplicated as well,
and since they are likely to appear while sysinst is running, are
also likely to mess up the display.
Can this sort of thing be necessary?!?
